Two-dimensional topological quantum field theories of rank two over Dedekind domains
arXiv:2502.04502
Abstract
We give examples of Frobenius algebras of rank two over ground Dedekind rings which are projective but not free and discuss possible applications of these algebras to link homology.
Minor sign typo in the first equation in (4.8), and the derived proceeding equations, have been fixed. 20 pages, 2 figures
